Description

Methods used to create pumpable items

The present invention relates to a method of making a smokable article in which the tobacco is shaken and an extrudate is formed, wherein the extrudate is coated on the shaken tobacco. the

The invention also relates to an apparatus for producing tobacco rods containing extrudates, which has a suction rod conveyor for smoking tobacco, an extrusion device for producing the extrudates and for coating the extrudates. On to the shaken tobacco. the

A method for producing cigarettes is known from DE 3311886 C2, in which a mixture of expanded tobacco paste is applied to a tobacco layer. It is also disclosed that the expandable tobacco paste can also be flavored, for example menthol. the

Known from GB 2070409A is a method for the manufacture of cigarettes, in which the fibers loaded with flavors, which can also be composed of tobacco sheets, are drawn from a winding reel and enter the tobacco rod before the specifications are introduced. the

As we all know, cigarettes are mixed with spices. This spice is released when it is drawn. Because the combustion temperature is higher when a cigarette is lit than when it is drawn, it is desirable not to release flavor when the cigarette is lit. the

In addition, it is important that the density of the tobacco in the cigarette is not significantly changed by adding a flavoring to the cigarette, and that the burning performance and ash forming characteristics of the cigarette are not adversely affected. the

It is therefore the object of the present invention to provide a method for operating a coiler by which an additive can be introduced into cigarettes depending on the location. A further object of the present invention is to provide a device for producing tobacco rods, with which additives can be introduced into a smokeable article in a position-dependent manner. the

Described task is solved by a kind of method that makes the coiling machine operation in tobacco processing industry, and method has the following steps:

- shake out the tobacco;

- Generate extrudates;

-applying the extrudate to shaken tobacco, wherein the extrudate comprises a base ingredient;

- and where the input additions to the base component are discontinuous. the

In addition, said object is also solved by a device for producing a tobacco rod containing an extrudate, wherein the device comprises a suction rod conveyor for smoking tobacco and an extrusion device for forming the extrudate and The extrudate is applied to shaken tobacco, wherein the extruder includes means for discontinuously delivering additives to a base composition which may be added to the extruder. the

The solution according to the invention makes it possible to position the additive in a position-dependent manner on the tobacco rod and thus also in the cigarette which is subsequently produced from the tobacco rod. The disadvantage of the prior art is avoided here: when the additive is continuously mixed into an extrudate, the additive is released when the cigarette is lit. Because the speed at which the tobacco rod or tobacco is conveyed, and the speed at which the extrudate is applied to the shaken-off tobacco, is known in the art, it is possible to make additives by feeding them discontinuously to the base material. The substance is located in the extrudate and thus later in the cigarette exactly. The additive can thus be placed or positioned in a position-dependent manner in the finished cigarette, thus ensuring that the release or burning moment of the additive can be influenced by discontinuous and controllable incorporation of the additive into the base component . For example, it may be necessary for the additive to be arranged over the entire length of the cigarette, whereas it may be necessary to release another additive only when lit, so that this additive only needs to be arranged within a very short distance from the beginning of the cigarette. These various requirements can all be realized by the method according to the invention. the

Tobacco may also be or contain other smokable materials within the scope of the present invention. In an advantageous refinement of the invention, the additive is supplied to the base component via a switchable device. This enables the discontinuous input of additives to be influenced. For example reconstituted tobacco of a paste-like consistency is suitable as a base ingredient. Reconstituted tobacco usually consists of water, tobacco fines and a binder. The consistency of the substance can be influenced by the water content. Examples of binders that come into consideration are: methylcellulose, dextrin glue, starch, polyvinyl acetate glue, polyvinyl alcohol or modified starch. In a further configuration of the invention, the extrudate can be composed of a plurality of different basic components, which are then combined with one or, if appropriate, also with several additives. If the extrudate is to be foamed, it is advantageous to mix two base components, one of which is mixed with calcium carbonate, for example, and the other with citric acid. the

In another advantageous embodiment of the invention, the additives are fed into the base component in a mixing device. The construction of the mixing device thus makes it possible to achieve a homogeneous incorporation of the additives into the base components to form the extrudate mixture. Furthermore, it is advantageously provided that the extrudate consisting of the base component and the additive is applied to the shaken tobacco via a nozzle device. The nozzle device is now connected downstream of the mixing device or is integrated in it, so that the final extrudate can flow out of the nozzle device, which is applied to the shaken tobacco. the

In a further embodiment of the invention, the additive is sprayed onto the extrudate intermittently. the

The additive mixed with the base ingredient is in particular a fragrance such as sugar, menthol, licorice, amino acids, cocoa or another substance that influences the fragrance or combustion behavior. the

In an advantageous refinement of the invention, the extrudate is fed to the tobacco at a speed which corresponds approximately to the speed at which the tobacco is conveyed in the suction rod conveyor. The position of the additive in the extrudate and subsequently in the tobacco rod is controlled and regulated by suitable devices, which are connected in series after the rod conveyor, for example by means of a cutting device of a coiling machine. the

The extrusion device preferably includes a mixing device, wherein additives can be introduced into the mixing device. the

In a special embodiment of the invention, the device for producing tobacco rods with extrudates has an openable valve with which additives can be fed intermittently to the base component. This valve is designed in particular as a quick-connect valve in order to precisely position the additive in the extrudate. Particularly suitable for this is a piezoelectric element, which is switched on by a control device, so that the additive is delivered exactly to the extrudate portion which is to contain the additive in the subsequent cigarette. Shaking the tobacco may continue after the extrudate is applied to the shaking tobacco. The tobacco fleece (Tabakvlies) thus formed is then trimmed and wrapped with a wrapping material in a rod forming device and formed into a shaped tobacco rod. the

The invention is explained below by way of example on the basis of exemplary embodiments with reference to the appended schematic diagrams, without restricting the general inventive concept. In addition, details according to the invention which are not described in detail in all published texts are expressly referred to in the drawings. Shown as:

Fig. 1: a kind of schematic diagram according to the device of the present invention;

Figure 1 shows a schematic diagram of an apparatus for manufacturing tobacco rods, in which an extrudate is added or incorporated, and which includes a rod conveyor 22 which continuously smokes tobacco 10 and A growing tobacco chip (Tabakschauer) is formed along its length. The tobacco 10 is now delivered to the suction rod conveyor 22 via the input device ( 27 ). Associated with the suction strip conveyor 22 is an extrusion device 13 . The extrusion device 13 is used to form or produce the extrudate 12 . Furthermore, the extrudate 12 is applied to the shaken tobacco 11 by means of the extruding device 13 . The extrusion device 13 includes a mixing device 14 to which the base component 16 is delivered. The base component 16 is empty from a storage container 25 to the mixing device 14 , for example via a pump 23 . the

The extrusion device 13 also includes a storage container 24 in which an additive, for example a fragrance 17 is stored. The additive 17 is delivered to a device 20 by means of a pump 23 . The device 20 is switched on by the control device 21 so that the additive 17 can be fed intermittently to the mixing device 14 . The switchable device 20 is designed in particular as a piezoelectric element, since this enables precise feeding of the additive 17 . Furthermore, provision is made to supply the mixing device 14 with another basic component 26 which is stored in a further storage container 25 and which is likewise fed to the mixing device 14 via a pump 23 . The base component 16 and the additive 17 are brought together or mixed together in the mixing device 14 . the

In an embodiment not shown, it is likewise possible to initially form an extrudate of its basic consistency and to spray the additives onto the extrudate in the mixing device. The mixing device 14 is connected to a nozzle device 15 . The nozzle arrangement 15 discharges the finished extrudate 12 at a predetermined extrudate velocity v2. The extrudate 12 is fed to tobacco fleeces built on a suction rod conveyor 22 . In an embodiment not shown, the additive can first be applied to the extrudate 12 in the nozzle device 15 or the extrudate can be sprayed with the additive 17 after the extrudate has emerged from the nozzle device 15. . After the extrudate 12 is applied to the shaken tobacco 11, other tobacco 11' is shaken onto the tobacco 11 and the extrudate 12. the

FIG. 2 shows a part of another configuration of the device according to the invention, in particular the application of the extrudate 12 to the shaken tobacco 11 here. The tobacco 11 can also be a fiber cake or a fleece, the tobacco being moved on a suction rod conveyor 22 at a tobacco transport speed v1. At a suitable location, where the tobacco 11 has a sufficient height, the extrudate 12 is applied to the shaken tobacco 11 . At the same time, the position of the extrudate 12 on the tobacco 11 is influenced by the orientation of the nozzle device 15 . Likewise, the diameter or the shape of the extrudate 12 flowing out can also be adjusted by means of a corresponding design of the nozzle device 15 . In FIG. 2 it is shown that the additive 17 is fed to the nozzle arrangement. the

Figure 3 shows a flow chart of a method for operating a coiling machine for the tobacco processing industry. In step S11, the prepared tobacco is sucked by the suction rod conveyor 22 and the tobacco 11 is shaken to form a kind of fleece. The tobacco 11 is transported on the suction rod conveyor at a tobacco transport speed v1. Parallel to this, the base component 16 or a plurality of base components 16 , 26 are fed to the mixing device 14 in the extrusion device 13 in a step S12 . Depending on the desired position of the additive 17 in the cigarette in the future, the quick opening valve 20 is manipulated by a control device 21, so that the additive 17 is intermittently added to the base component 16 (S13). In step S14 the prepared extrudate 12 is discharged from the nozzle device 15 . In step 15, the extrudate 12 from the nozzle device 15 is applied to the tobacco 11. Further processing steps on the tobacco rod comprising the tobacco 11 and 11' and the extrudate 12 are carried out in step S16, these steps being followed by the rod conveyor 22. This includes, for example, encapsulation with encapsulation materials. In step 17, the tobacco rod is cut corresponding to the position of the additive 17 in the extrudate 12, thereby forming a tobacco rod wrapped with a wrapping material (S18), wherein the additive, especially the flavor 17, depends on Positionally located and therefore not released, for example, when a prepared cigarette is lit, but only released when the cigarette is drawn. the
